    This is an interesting fallacy that I see all of the time - 'go back to paper'. Let's face it - the ONLY way you can run a modern airline, hospital, utility or whatnot is with a computerized system.

    There is a modern airline - Air France I think, that does just this. Their systems fail often, but they have a robust paper system to keep people from being stranded.

    Thing is, you don't to allow people to buy new tickets in order to function. Lots of what a modern airline does can just be ignored. You need to verify tickets and boarding passes - which can be done by straining the phone network back to a central office with lots of temp workers, and you need to keep aircraft inspection/maintenance logs current, but that's still mostly paper anyhow.

    You can make very complex systems work without computers if you care enough to do so. You can also make disaster recovery systems that actually work when you need them - though you do need to follow the expensive advice of professionals, so maybe some corporations are culturally incapable.

    You do realize that you don't know what a Go board looks like either, right? Human consciousness is far removed from raw sensory data. You have a software abstraction that represents the board, just like AlphaGo. Sure, your derives from sensory data, but it would be trivial these days to have the AI use an actual Go board, a camera, and a robotic arm to play - those are all solved problems, not interesting ones.

    Also, you want a different term than "AI" if you want to mean consciousness. The "artificial" in AI means "doing it anyway, without consciousness". At least, that's what it means to experts in the field. SF writers and philosophers abuse the technical term, but on Slashdot we should endeavor to use technical terms related to CompSci correctly.

They're doing the practical job of solving problems using computers - problems that aren't obviously solvable without consciousness, but that they're nevertheless trying to solve without consciousness.

    Actually, it is not. This approach does not work with "knowledge" or "skill". It works in an automated way which involves neither. It could be printed in a book and executed purely mechanically. Or would you claim a book can be "intelligent"?

    And by book you mean Chinese room, right? And you do realize that AlphaGo doesn't play by using a deep set of lookup tables, right? Much like a human player, it has a way of scoring possible play that doesn't involve canned openings or evaluating every combination N moves ahead, but instead by evaluating what play seems weak or strong.

    There is no useful definition of "knowledge" or "skill" that excludes what AlphaGo does, unless you assume your own conclusions about human intelligence. There's certainly something we call "self awareness" that the AI doesn't have (thus the "A" in "AI"), but it's not related to playing Go.

    Oh, sure, the way AlphaGo's neural net does pattern matching, and the way your neural net does pattern matching aren't identical. But they are functionally equivalent, in the domain of "playing Go". I think you'll find little difference in the choices human players make (in "accurate" play) and AlphaGo makes, other than AlphaGo being less bound by habit and more likely to surprise.

    Without asserting the supernatural, all you can say here are "different implementations, functionally equivalent".

    If you want to call that evidence, fine, but it's extremely weak evidence. Weak to the point of being unworthy of serious consideration. Certainly not strong enough to reject the null hypothesis ("not aliens").

    That's not how this works. Science work by advancing a collection of hypotheses to explain any unexplained data point - as long as the hypothesis fits existing data, anything goes. You cull the collection once you have more data - which one predicted it successfully, which one was falsified. "Alien superstructure" fits the available data and is falsifiable, so it's on the list. For now.

    Subjective "well, I don't think that one's likely" judgement calls may influence personal choices of what to pursue in the meantime, but only observations can falsify a hypothesis.

    What they didn't do was make a handful of observations and then trumpet the most improbable of possible explanations that hadn't yet been ruled out into the mass media. They got to quantum mechanics gradually and with careful effort over many decades.

    Never confuse science journalism with scientists.

    Planck's law was really out there at first - Planck didn't even have an explanation for why there would be a connection to statistical distributions - no underlying model - just a "hey, the math works, so maybe". Most of the key work for quantum physics happened very quickly after that - any revolutionary change in a field takes 20ish years, but the foundational work was complete 100 years ago. It took several decades to understand and accept that the universe really was a crazy as the story that QM tells, and to tame the math needed.

    Have you actually ever formally studied logic and meta-logic? It's also a fun field.

    Much of scientific progress has been made by taking a long jump away from established theory to explain some measurement that doesn't fit. Quantum mechanics tells a very strange story indeed, one discordant with pretty much everything in ordinary experience and most scientific fields. Yet it was the right answer to the puzzle of blackbody radiation curves.

    The problem is that you're not really predicting human behavior in a deterministic sense, but a statistical one.

    The Higgs Boson was not observed in a deterministic sense, but a statistical one (you know there's no "Higgs Boson detector, right?). Heck, quantum mechanics tells us that the universe we live in allows only observations that are statistical rather than deterministic, and most of its weird results are where that is made obvious.

    "Soft sciences" as you call them, seem more like scientism when strict scrutiny is applied to them.

    Well, I can hardly argue whether they meet the definition of some word you made up, can I? But there's nothing wrong with statistical measurement - zoom in enough and you see it's the only kind of measurement possible.

    Furthermore, modern science is at odds with your statement that unlikely is a bad theory. You say it is easy, but we can't even cheat and reproduce the circumstances that create it in a lab in order to reverse engineer the environmental circumstances that would allow it to happen. It appears to be quite difficult, even if you already have life on hand to study.

    Well, it did take half a billion years or so. Fairly fast in geological terms, but I gather scientists are running somewhat shorter experiments.

    Simply put, if we don't know how it came about, we can't estimate how likely it is to occur elsewhere.

    Sure we can. It must be fairly likely, because you're nothing special.

    In regards to "dissonance theory", what observations would show it was wrong?

    I listed the discordant results. Dissonance theory failed to explain differences in measurement of people who held the same beliefs, but were different in another way. People who had more beliefs in a area are more likely to reject information that disagreed with their biases (that sort-of fits, but didn't fit the formal way the theory was stated). People who were more involved -- that is, it mattered more to their lives if they were wrong -- were more likely to disagree with their biases. People were more likely to reject information that went against claims they had made publicly.

    The theory was "modified" in a series of step with a series of new results. (Once a theory has been around a while, it's rarely just thrown out entirely, in any field, instead it's "modified", much less damaging to careers).

    Do you see the pattern? A theory that predicts human behavior is easily falsified by observing human behavior in controlled conditions. Simple as that. Making theories that don't get falsified over time is a different matter, one which the soft sciences still aren't good at.

    The unlikely transition seems to be multi-cellular life. Life on Earth started very early, evidence that it isn't that hard. Multi-cellular life to the Cambrian explosion took a while, but its seems evolution was fairly steady, trying out lots of body patterns.

It matters how involved the subject is with the topic; it matters how much the subject already knows about the topic, and so on.
